DuraTough DL



FLEXICLAD DuraTough DL is a two component, 100% solids, fluid consistency elasto-ceramic polymer composite specifically formulated to surface and protect equipment subject to cavitation accelerated erosion/corrosion.

DuraTough combines the superior strength, durability and adhesion of an epoxy with the exceptional flexibility, abrasion resistance and shock absorbency of an elastomeric urethane.

Flexiclad DuraTough DL is ideal for coating, resurfacing & protecting equipment prone to cavitation attack as well as creating and repairing flexible seals, gaskets, seats, etc., on machinery and equipment such as heat exchangers, pumps, valves & piping systems.
